XADOEngine Oil System Cleaner with Anti-Carbon Effect - Removes Contamination & Engine Sludge - ATOMEX Total Flush Revitalizant (Bottle, 250ml)

Product worked instantly (2 nuggets of carbon came out in addition to engine oil was completely black even though I had just changed the oil within 1 month, engine noise level went down, car feels like it has more power) car has 200k miles and this was the first time I’ve cleaned an engine cleaner. I will be using it regularly.

So I was slacking quite a bit with my oil changes for reasons I'm not going to put on here but, basically, it has been like 25k miles since I did my last oil change. The oil I was using was rated to stay above industry minimum standards for 20k miles and that was about 5k more than what the oil was rated for. I noticed my car was starting to decrease in fuel economy so I decided to try this out. Did an oil change, dumped this in, drove for just over 100 miles, did another oil change, and now I'm back to getting the fuel economy my car got when I first got it. Went from getting like 38 MPGs back up to between 46 and 51 MPGs averaged ever since I did that. This stuff works! I'm glad I bought it! If you're a little behind on your oil changes, definitely throw some of this in! It really helped me! Decided to wait a little bit before reviewing to make sure it wasn't just confirmation bias and that I truly was consistently seeing the improved gas mileage again and I am. Put it in my car about a month and a half ago and the results have remained the same. It wasn't confirmation bias and it wasn't because I changed the way I drive, it really did help. Now, of course this isn't going to get you better fuel economy than what your car originally came with but if your dirty oil system is what is causing lower fuel economy, it should bring it back to like new if you use it like I did. Definitely do your oil changes when you're supposed to but if you can't, this makes it not as big of a deal so long as you don't go too far past what the oil is rated to. I definitely recommend this!

Did great job of cleaning out / flushing contaminants / carbon deposits out of oil.The Waste oil was practically black.SUV had carbon build up due to excessive idling due to daily commuting.Additionally injectors cleaned at Shop .

I have a problem with the oil rings. I hoped the problem would be solved, but after 50 miles with this product, a miracle did not happen.

Works great

Bought a used 2018 Jeep Wrangler Unlimited Rubicon for my daughter with 50,000 miles. Carfax said oil had been changed every 7500 miles so I wanted to flush the lubrication system. Did some research and thought this product might do the job. It worked perfectly. Left it in for 50 miles and drained the oil. Wow was it black. Bought some Amazon basics 0w - 20 oil and filter and changed oil. running for 500 miles and will change again. I normally run Royal Purple in all my vehicles, I think its a great lubricant based on testing, so I will change out soon. When you used chemicals inside a motor its always good to flush them out with what I call a flush oil change before you go to your preferred oil. 5 stars!Fast forward 6 months, product worked really well. Switched over to Royal Purple 0w-20 and change oil every 5000 miles. Engine runs smooth and no valve tick. Consistency get 18 -20 mpg in Jeep wrangler Rubicon v6 2018. When I drain out the oil it still looks good. Product works well!!!!!!

My vehicle had 130,000 miles on it, but I changed the oil frequently so it really didn’t make a difference when I use this product. I use it as simply as a maintenance product.

Have a BMW 328i with N52NA engine and used many engine oil cleaners over the years and they didn't seem to do much. Used XADO once and a huge difference. Lifter knock disappeared and oil burn went away (cleaned junk from oil rings). I won't be using anything else from now on for this or my other car.
